I am actually really excited for the Morde rework
I understand that my opinion is unpopular and I will probably get downvoted to oblivion for saying this, but I think this patch for Morde is one of the coolest things Riot has done in years. I'll preface this by saying that I don't really agree or disagree with their changes on Morde specifically, but this is the first time since Season 1 where Riot has actively encouraged players to use a champion in bot lane besides a ADC. I played this game since beta, and one thing I really miss, despite all of the flaws the game had at the time, was the ability to pick any type of lane composition that you wanted. It wasn't uncommon to see bot lanes of Taric/Sion or Blitz/Alistar -- champions that complemented each others' strengths perfectly - there wasn't this huge desire that there absolutely had to be an AD carry on every team, and one of the strongest team compositions at the time involved no ADCs at all - Janna/Taric/Soraka/Alistar/Heimer for endless healing and pushing. This obsession with ADCs has made the game so stagnant that almost everything revolves around it.
This is the first time that they're actively doing a part in shaking up the meta - if they can make just one champion viable in bot lane other than an ADC, that is going to be huge for opening up the meta and giving players infinitely more options for how they want to play. I personally really hope that Morde is a viable bot laner, because that is going to do one of the biggest changes to this game since that Dreamhack tournament where the meta as we know it became the only way to play the game. I know that we as a player base can technically pick whatever we want in whatever lane we want, but in practice, in a ranked match, if you pick outside the meta, you are taking a risk that someone will freak out, troll, and turn the entire team against you, ensuring that not only will you lose the game, but you'll also get reported and risk losing your account as well.
I get that people that really liked Morde are pissed, and justifiably so - I used to be an Evelynn main before they nerfed her, left her in the gutter for a year, then completely redesigned her into a Shyvana wannabe with a weak stealth. I was pissed as hell about what they did to Evelynn, and I can empathize with people who liked Morde as much as I liked Eve, but the benefits from the Morde rework (if it's successful) are huge.
